3. Dimensions (in mm): Ø 8.13
4. Radiant sensitive area (in mm2): 7.5
5. High photo sensitivity
6. Adapted to human eye responsivity
7. Angle of half sensitivity: ϕ= ± 50°
8. Hermetically sealed package
9. Cathode connected to package
10. Flat glass window
11. Low dark current
12. High shunt resistance
13. High linearity
14. Compliant to RoHS Directive 2002/95/EC and in accordance with WEEE 2002/96/EC

Applications

1. Sensor in exposure and color measuring purposes

ULN2803LW Darlington

 

Description :

Featuring continuous load current ratings to 500 mA for each of the drivers, the Series ULN28xxA/LW and ULQ28xxA/LW highvoltage, high-current Darlington arrays are ideally suited for interfacing between low-level logic circuitry and multiple peripheral power loads. Typical power loads totaling over 260 W (350 mA x 8, 95 V) can be controlled at an appropriate duty cycle depending on ambient
temperature and number of drivers turned on simultaneously. Typical loads include relays, solenoids, stepping motors, magnetic print hammers, multiplexed LED and incandescent displays, and heaters. All
devices feature open-collector outputs with integral clamp diodes.
